      This product has been discontinued.






      Recombinant, human JAK3 fused at the N-termiunus to a GST-His6-thrombin cleavage site sequence and expressed in S. frugiperda insect cells using a baculovirus expression system. JAK3 is a member of the Janus family of tyrosine kinases and plays an important role in signal transduction and interacts with members of the STAT (signal transduction and activators of transcription) family.

      Recommended reaction conditions
      96-Well Membrane Binding Kinase Activity Assay Protocol:
      Materials Required Standard Kinase Assay Buffer: 125 mM HEPES-NaOH, 7.5 mM MgCl2, 7.5 mM MnCl2, 7.5 µM sodium -orthovanadate, 2.5 mM DTT, pH 7.5 10X Kinase Dilution Buffer: 500 mM HEPES-NaOH, 2.5 mg/ml PEG20.000, 10 mM DTT, pH 7.5 Substrate: R11-VYSTDYYRLFNPS), 2.5 µg/50 µl final concentration JAK3, GST-Fusion, Human, Recombinant, S. frugiperda, diluted in 10X Kinase Dilution Buffer to desired concentration (we use 200 ng in a 50 µl reaction) 33P-γ-ATP ATP Mix: 1 µM ATP in H2O with 1 x 106 cpm/5 µl 96-well V-bottom MTP (polypropylene) plates (Nunc Cat. No. 442587) 96-well Multiscreen Vacuum Manifold (Millipore Cat. No. MAVM096OR) 96-well Multiscreen Filterplates, phosphocellulose membrane (Millipore Cat. No. MSPH N6B50) and glass fiber (Millipore Cat. No. MSFC N6B50) 2% H3PO4 0.9% NaCl
      Activity Assay Protocol 1. In a polypropylene V-bottom plate add 20 µl Kinase Assay Buffer 2. If desired, add 5 µl test substance (e.g., inhibitor, activator, etc.; in 10% DMSO) 3. Add 10 µl Substrate (diluted in H2O). 4. Add 10 µl diluted JAK3. 5. Add 5 µl ATP Mix. 6. Mix on a shaker and incubate at 30°C for 80 min. 7. Stop the reaction with 50 µl H3PO4. 8. Prewet the filter plate with 200 µl H2O. 9. Filter the reaction mix by applying vacuum. 10. Wash 3 times with 200 µl 0.9% NaCl. 11. Add 200 µl scintillation fluid to each well and count on a scintillation counter.
